Hi, I just purchased a M700 Sendero SF II in 7mm Rem Mag. It's going to be a lil while till I actually get to shoot it though. Saving to purchase a scope right now. I'm looking for some load data since this will be the first I've loaded for this round. I'm planning on using Norma brass and want to start out with the 168 and 180 Berger VLDS. I'm not sure which powder selection would be best to start with though. I currently have a jug of IMR 4350 I could try but I've also have heard that Retumbo is suppose to be a good powder for the 180's. Any thoughts or advise would be appreciated.
